Abstract

In the generator (2) with axial magnetic flux the two magnet plates (4, 6) rotate at both sides of the stator (8). The latter has an iron core and spools. The magnets (10, 12, 14, 16) lie exactly with the north poles opposite north and the south poles opposite south. Thus, the flow of the magnetic force lines through the spools (18, 20) from the magnetic fields of the plate (4, 6) is optimal. If the magnet plates (4, 6) are radially displaced with respect to each other, the field strength of the magnetic force lines changes accordingly. The field strength which acts on the individual spools is reduced as the plates (4, 6) move towards each other and the induced voltage is thus reduced. ADVANTAGE - Inexpensive, compact and lightweight. Can be used for all power ranges. Allows step-free control. No electric interference pulses with pneumatic or hydraulic control. No additional loss.

Description

Die Erfindung betrifft eine Einrichtung zur Spannungsregelung von Generato­ ren mit Permanentmagneten.The invention relates to a device for voltage regulation of generato with permanent magnets.

Permanentmagnetgeneratoren haben die Eigenschaft, daß sie je nach Bela­ stung eine unterschiedliche Spannung liefern. Die meisten elektrischen Ver­ braucher erfordern eine elektrische Spannung, die relativ stabil sein muß und nur einige Prozent schwanken darf. Dieses Problem wird in der Regel durch folgende Maßnahmen gelöst:Permanent magnet generators have the property that depending on the Bela supply a different voltage. Most electrical ver consumers require an electrical voltage that must be relatively stable and may fluctuate only a few percent. This problem is usually caused by solved the following measures:

  • - Spannungsregelung durch Regelelektronik Nachteile: relativ hohes Gewicht, komplizierte Schaltung, Beein­ trächtigung des Gesamtwirkungsgrades durch Verlustwärme, großes Bauvolumen durch Kühlflächen, aktive Kühlung durch Ventila­ tor erforderlich, hohe Herstellungskosten, hohe Störimpulse, anfäl­ lig bei Laständerungen - Voltage regulation by control electronics Disadvantages: relatively high weight, complicated circuit, legs Impairment of the overall efficiency due to heat loss, large Construction volume through cooling surfaces, active cooling through Ventila gate required, high manufacturing costs, high interference, accrued lig with load changes  
  • - Aufbau eines magnetischen Gegenfeldes Nachteile: ähnlich wie bei der Regelelektronik- Construction of an opposing magnetic field Disadvantages: similar to control electronics
  • - Regelung durch Drehzahländerung Nachteil: nicht anwendbar bei Antriebsaggregaten, die mit konstan­ ter Drehzahl laufen (müssen).- Regulation by changing the speed Disadvantage: not applicable to drive units with constant speed (must) run.
  • - Änderung des Luftspaltes zwischen Permanentmagneten und Eisenkern Nachteile: großer Aufwand, teuer.- Change in the air gap between permanent magnets and Iron core Disadvantages: great effort, expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Spannungs­ regelung zu schaffen, die die angegebenen Nachteile vermeidet und auch bei hohen Generatorleistungen realisierbar ist.The invention has for its object a device for voltage create regulation that avoids the disadvantages indicated and also at high generator power is feasible.

Bei einem Permanentmagnetgenerator mit Zweischeibenläufer und axialem Magnetfluß und axialem Luftspalt wird diese Aufgabe dadurch gelöst, daß die Magnetscheiben radial gegeneinander verschiebbar sind.In the case of a permanent magnet generator with two-disc rotor and axial Magnetic flux and axial air gap this problem is solved in that the Magnetic disks are radially displaceable against each other.

Durch diese Regelung ergeben sich folgende Vorteile:The following advantages result from this regulation:

  • - kostengünstig- inexpensive
  • - platzsparend, geringes Gewicht- space-saving, light weight
  • - für alle Leistungsgrößen einsetzbar- Can be used for all output sizes
  • - stufenlose Regelung möglich- stepless regulation possible
  • - bei pneumatischer oder hydraulischer Ansteuerung entstehen keine elektrischen Störimpulse- arise with pneumatic or hydraulic control no electrical interference
  • - der Gesamtwirkungsgrad des Generators wird nicht beeinträchtigt; es entsteht keine zusätzliche Verlustleistung.- The overall efficiency of the generator is not affected; there is no additional power loss.

Die Erfindung wird nachfolgend anhand von Fig. näher erläutert.The invention is explained in more detail below with reference to FIG .

Fig. 2 und 3 die magnetischen Kraftlinien und den Magnetfluß bei einem Permanentmagnetgenerator mit fluchtenden Magnetscheiben, Figs. 2 and 3, the magnetic lines of force and the magnetic flux in a permanent magnet generator with aligned magnetic disks,

Fig. 4 und 5 die magnetischen Kraftlinien und den Magnetfluß bei einem Permanentmagnetgenerator mit radial gegen­ einander verschobenen Magnetscheiben. FIGS. 4 and 5, the magnetic lines of force and the magnetic flux in a permanent magnet generator with radially shifted against each magnetic disk.

Bei einem Zweischeibenläufer-Permanentmagnetgenerator 2 mit axialem Magnetfluß (Fig. 1) drehen sich die beiden Magnetscheiben 4 und 6 zu bei­ den Seiten des Stators 8, der aus Eisenkern und Spulen besteht. Die Mag­ nete 10, 12, 14, 16 (Fig. 1 bis 3) liegen exakt mit den Polen Nord auf Nord und Süd auf Süd gegenüber. Dadurch wird erreicht, daß die Spulen 18, 20 von den magnetischen Feldern der Magnetscheiben 4 und 6 optimal von den magnetischen Kraftlinien durchflossen werden. In Fig. 3 sind die ansteigen­ den und abfallenden Stromflanken dargestellt.In a two-disk rotor permanent magnet generator 2 with axial magnetic flux ( FIG. 1), the two magnetic disks 4 and 6 rotate toward the sides of the stator 8 , which consists of an iron core and coils. The Mag nete 10 , 12 , 14 , 16 ( Fig. 1 to 3) are exactly opposite with the poles north to north and south to south. It is thereby achieved that the coils 18 , 20 flow through the magnetic fields of the magnetic disks 4 and 6 optimally by the magnetic lines of force. In Fig. 3 the rising and falling current edges are shown.

Werden die Magnetscheiben 4, 6 radial gegeneinander verschoben, so ändert sich die Feldstärke der magnetischen Kraftlinien. Die Feldstärke, die auf die einzelnen Spulen wirkt, wird reduziert (Fig. 4). Daraus ergibt sich, daß die induzierte Spannung sinkt.If the magnetic disks 4 , 6 are displaced radially against one another, the field strength of the magnetic lines of force changes. The field strength that acts on the individual coils is reduced ( Fig. 4). As a result, the induced voltage drops.

In Fig. 5 ist die ansteigende und abfallende Stromflanke im zeitlichen Verlauf dargestellt. Der Regelbereich lag bei eine 5-kW-Testgenerator bei 60% des Spannungsbereiches.In FIG. 5, the rising and falling current edge is shown over time. The control range for a 5 kW test generator was 60% of the voltage range.
